Thomas Mastro, 24, of the 6900 block of Coachwood Trail, died Thursday after he was shot in the parking lot of a 7-Eleven less than a mile from his home. The Cook County Medical Examiner's office released Mastro's name, and an autopsy showed he died of a gunshot wound to the chest in a homicide.

Mastro's father, Perry Mastro, said Mastro was the father of a 4-year-old son, and was engaged to marry his girlfriend of five years. Mastro worked as an independent contractor.

"He was a good kid, a father himself," Perry Mastro said.

A suspect who was taken into custody Thursday after an hour-long manhunt should be charged by Saturday, Tinley Park police said. Police still are investigating the shooting.

Police said the suspect shot the victim as the two argued in the parking lot of the 7-Eleven, 16658 S. Oak Park Ave., then drove off.

A customer at the 7-Eleven flagged down an off-duty police officer, who was in a marked squad car, and gave a description of the suspect's vehicle, according to Tinley Park Police Cmdr. Steve Vaccaro. The officer spotted the car and chased the suspect north on Oak Park Avenue.

The suspect abandoned his car in the parking lot of Jack Gibbon's Gardens, a restaurant on 147th Street and Oak Park Avenue in Oak Forest, and bolted into the nearby forest preserve. Expecting backup to arrive, the Tinley Park officer waited with the suspect's vehicle, Vaccaro said.

More than 50 officers from a dozen surrounding communities searched the woods, including six search dog teams and the Cook County/Chicago Police helicopter.

The search went on for nearly an hour, when two officers stationed at the perimeter of the park near 143rd Street spotted the suspect attempting to leave the woods. The officers, from Orland Park and Oak Forest, chased the suspect into the woods, and apprehended him, Vaccaro said.

Police located a weapon near 159th Street and Oak Park Avenue, Vaccaro said.

The victim was taken to Palos Community Hospital in Palos Heights, according to a press release from the village, where died from his wounds.

"We are shocked and saddened at this heinous crime, but we're glad the suspect was apprehended as quickly as he was," Tinley Park Mayor Edward Zabrocki said in the statement.
